shared_future& operator=( shared_future&& other ) noexcept; | (2) | (since C++11)

Assigns the contents of another `shared_future`.

1) Releases any shared state and assigns the contents of other to *this. After the assignment, this->valid() == other.valid().
2) Releases any shared state and move-assigns the contents of other to *this. After the assignment, other.valid() == false and this->valid() will yield the same value as other.valid() before the assignment.

### Parameters

other | - | a `std::shared_future` that will transfer state to *this

### Return value

*this
